Infusion needles for high penetration trees

Abstract

The invention discloses a high-penetration infusion needle for trees. The high-penetration infusion needle for trees is characterized in that the infusion needle includes a needle and a press board; the needle is internally provided with a flow channel extending forward, and the front end of the flow channel is plugged to form a cone head; the wall of a side, near the cone head, of the flow channel is provided with strip-shaped liquid outlets of which the direction is consistent with the axis of the flow channel; the rear end of the flow channel is connected with an annular interface, a platform perpendicular to the flow channel is arranged in the annular interface, and a hose interface is arranged on the side of the annular interface; the press board is connected to the open side of the annular interface in a sealed manner; and the platform is provided with bulges distributed around the rear-end opening of the flow channel, and the bulges abut against the inner surface of the press board. With the high-penetration infusion needle, trunk tissue fibers are not cut off, later wound healing and growth are facilitated, and hole blocking is not caused. During use, the press board can be pressed to transfer force to the needle through the bulges, so that the needle can be inserted into a trunk more easily.

Description

technical field [0001] The invention relates to a device for infusion in the field of tree and plant protection, in particular to a needle for infusion with high permeability for trees. Background technique [0002] Our country is a large forestry country, and fruit trees are widely planted. With the improvement of planting technology, when the seedlings are transplanted or in their critical growth period or when diseases occur, in order to make the trees grow healthily, it is often necessary to infuse them to provide them with the necessary water, nutrients or Drugs, thereby greatly improving the survival rate and growth trend of trees, have obvious effects on increasing production and increasing efficiency, especially the cultivation of some trees with high economic value is inseparable from infusion maintenance, so infusion technology is especially important. The existing tree infusion is also like human infusion. The nutrient solution or medicinal liquid is input into th...

Problems solved by technology

The existing tree infusion is also like human infusion. The nutrient solution or medicinal liquid is input into the trunk through the needle inserted into the trunk, and then transported from the tissue in the trunk to the crown, which is conducive to the rapid absorption of the tree. Although the existing tree infusion methods are already very common , but its infusion equipment does also use equipment similar to human or animal infusion, such as bagged nutrient solution, dropper and injection head, but the injection head is relatively thick, and it is very laborious to insert the injection needle due to the hard trunk, and the needle It is also easily blocked by the tissue fibers in the trunk. For this reason, people will drill holes on the trunk before giving the tree infusion, and then insert the injection needle in the hole. Sometimes multiple holes will be drilled for fast absorption. Although drilling is helpful It is suitable for infusion, but the damage of drilling cuts off the tissue fibers in the trunk, which is not conducive to the subsequent water transportation from the root to the crown. It is easy to form nodules at the drilling site and affect the growth of trees. This still needs to be solved technically.

The closest prior art patent document (publication number CN203027784U) discloses an adjustable infusion needle for trees. The front end of the adjustable infusion needle for trees is distributed with strip-shaped liquid outlets in the same direction as the axis of the flow channel. The extruding force of the tree fiber is relatively large, if the strip-shaped liquid outlet is made too long, it will be squeezed and deformed by the tree fiber. Such a needle structure has low strength, which will affect the penetration of the infusion
